DOT-5

OK,
I've got a complete new brake system.
76 Corvette master cylinder (non-power)
All new lines
91 Lumina calipers and rotors (pinion brakes on Rockwell's)

I understand that heat is a major factor on pinion brake systems. I also understand that it's the fluid that heats up causing brake fade. My question is:

Are the heat properties of DOT-5 fluid worth the PITA of it not being readily available?

Re: DOT-5

dot 5 is a silicone base fluid
it does not absorb water like the dot3 and 4
this can cause problems in a system that is not made with all aluminum and stainless steel components.

the water will collect in the system thru condensation as it cools and remain in the lowest points in the system. ie calipers causing premature sticking

The dot 3-4 fluids will do just fine over time as long as you take care of the system and flush it every once in a while. Dot3-4 is not compatible with dot 5

the other cool thing about dot 5 is that it does not remove paint like dot 3 or 4

Re: DOT-5

Do you have any info on the heat properties?
I knew the downside for the most part, I just wasn't sure how much of a trade off I was getting if I used it. My biggest concern was not being able to borrow any on the trail. [img]images/graemlins/grin.gif[/img]

Aaron,,, thats why you should carry enough for your use [img]images/graemlins/blush.gif[/img]

In any case if you have to borrow some you may have to borrow enough to flush the dot5 out [img]images/graemlins/wall.gif[/img]
